I also used to be plagued by numerous messages about hosts all
over our network being shut down. These messages actually come
to you courtesy of an RPC program called "rwall" (remote "wall"),
which "shutdown" calls to send messages to remote hosts which it
thinks might be interested.
One easy way to avoid getting any such messages is to disable the
rwall daemon that runs on your workstation (rwalld). You can do
this by commenting out its entry in your /etc/inetd.conf file and
then reinitializing inetd by sending it a SIGHUP signal.
A less extreme approach might be to have your rwall daemon run as
something other than root (the userid for running an inetd service
is specified in inetd.conf), so that you can selectively disable
its messages with "mesg n" (I haven't tried this approach, so I'm
not 100% sure that it works).
Cheers..Y
